Sinopse

Hydrogen can be produced from water and sunlight in two ways: 1 Thermal, in a highly purified reactor, using electricity from renewable sources (solar, wind, or hydro) to split water into hydrogen and oxygen through electrolysis, and using the heat from this process to generate steam 2 Photoelectrolysis, a method for producing hydrogen by using sunlight to catalyze electrolysis of water In either process, the only waste product is pure water WHERE CAN WE FIND HYDROGEN? Hydrogen is the most abundant element in the universe It is not a fossil fuel and is not derived from any oil or natural gas There are several methods of extracting hydrogen from water: 1 Electrolysis This is the only method of producing hydrogen that is both energy efficient and non-polluting Hydrogenation When hydrogen is passed over a catalyst, it combines with carbon monoxide to produce a mixture of hydrocarbons The mixture can be used as a fuel 3 Steam reforming This process can be used to produce hydrogen from methane
